摘要: 采用阶梯热处理的方式对Bi2O3-SiO2基玻璃进行析晶处理, 得到了具有不同结晶率和透明度的Bi4Si3O12(BSO)基玻璃陶瓷。实验表明, 分段热处理有利于控制BSO基玻璃陶瓷中晶粒的数量和尺寸, 从而影响玻璃陶瓷的透明度和发光性质。分段热处理后样品的透射谱显示, BSO基玻璃陶瓷(在600℃保温1 h, 然后升温至800℃保温1 h)的透过率可达73.1%(λ > 500 nm)。制备出的BSO基玻璃陶瓷具有和BSO单晶相似的发光性质, 在可见光波段(380~680 nm)有发光, 且发光强度与结晶率成正比。低温(14 K)下, 该BSO基玻璃陶瓷的发光强度较室温下提高了约12倍。

Abstract: Bi4Si3O12-based glass-ceramics with different crystalline volume fractions and transparency were prepared by the two-step heat-treatment of Bi2O3-SiO2 based glass. The experimental results show that the two-step heat-treatment is favorable to control the amount and size of crystallized grains in BSO-based glass-ceramics, which correspondingly affects the transparency and optical properties of the obtained glass-ceramics. The transmission spectra of these samples indicate that the transparency of BSO-based glass-ceramic (annealed at 600℃ for 1 h, then heated to 800℃ and held for 1 h) can reach 73.1% (> 500 nm). The BSO-based glass-ceramics maintain similar optical property as that of BSO single crystal, that is, the emission of such glass-ceramics is located in visible light wavelength of 380–680 nm, and their optical intensities are almost proportional to the crystalline volume fraction. The optical intensity of BSO-based glass-ceramic at low temperature (14 K) is increased by 12 times as against that at room temperature.
